Explain how the sodium/potassium exchange pump in the axon of neurons
maintains polarity. (2 marks)
Explain why polarity in an axon is necessary.
According to the research, the correct option is that the sodium-potassium pump is an ion exchanger, passing sodium ions (Na+) to one side of the membrane and moving potassium ions (K+) in the opposite direction, exerting polarity changes in the membranes.
What are the sodium/potassium exchange pumps?It is a physiological event that takes place between cells, during which an exchange of potassium ions for sodium ions occurs, being essential for the execution of the action potential, necessary for the transmission of electrical impulses from neuron to neuron.
In this sense, to act as an enzyme and be able to serve as a transport for NA and K ions, it needs the hydrolysis of ATP, leaving potassium ions on the side of the cytoplasm said polarity, generates a flow that allows the transmission of electrical potential , that is, the nerve impulse that moves the muscles.
Therefore, we can conclude that according to the research, the correct option is the sodium-potassium pump is an ion exchanger, passing sodium ions (Na+) to one side of the membrane and moving potassium ions (K+) in the opposite direction, exerting polarity changes in the membranes.

demonstrate the law of independent assortment by listing the 4 alleles that are produced when a pea plant with the Genotype YyRr produces gametes
Answer:
Mendel used the dihybrid cross between a homozygous pea plant with yellow round seeds and a homozygous pea plant with green wrinkled seeds. The parents have the alleles YYRR and yyrr, respectively.
During meiosis, the chromosomes are separated so that only half the genes are transported to the gametes. The possible genotypes of the gametes then become YR and yr.
As the parents are crossed, the fusion of the gametes results in the F1 hybrid with the YyRr genotype.
Explanation:
The F1 hybrids have the phenotype of yellow round seeds as the dominant allele Y for yellow color, and the dominant allele R for the roundness is expressed.
The alleles in F1 hybrids can now be segregated into four parts; Y for yellow color, y for green color, R for roundness, and r for wrinkledness.
The four alleles can combine in several combinations to produce different genotypes and phenotypes.
On further crossing, four types of gametes can be formed; YR, Yr, yR, and yr. These gametes fuse to form sixteen individuals in the F2 generation.
The ratio of the F2 hybrids is 9 yellow round: 3 yellow wrinkled: 3 green round: 1 green wrinkled.
This proves that both characters are inherited independently of one another and are expressed according to their dominance.
are most chemical reactions in living cells at equilibrium
No, equilibrium chemical reactions do not exist in living cells.
Define chemical equilibrium.Chemical equilibrium refers to the situation in a chemical reaction where both the reactants and products are present in concentrations that have no further tendency to change over time, preventing any discernible change in the system's properties. When the forward reaction and the reverse reaction go forward at the same speed, this condition results. The forward and backward reactions typically have equal, if not zero, reaction rates. The concentrations of the reactants and products do not change on a net basis as a result. Dynamic equilibrium is the name given to such a situation.

Scenario: Researchers posted ads in the newspaper to recruit participants for their study of a new treatment for agoraphobia (the fear of open places). 87 people responded to the ad, but only 60 of those actually reported being agoraphobics. Of the sixty, 20 were randomly placed in a condition (NEW) in which they received the new treatment. It was explained to the NEW participants that the treatment they would be receiving was promising but new, so they would be monitored carefully to watch for any undesirable side effects. Twenty other participants were assigned to a condition (OLD) in which they received an older, more traditional form of treatment. These participants were told that they were not receiving the new treatment but an older treatment that had been around for awhile, so the chances of side effects were minimal. Finally, 20 other participants were randomly assigned to a group (NO) that received no therapy. After six months of treatment, researchers found that the participants in the NEW condition were exhibiting 64% fewer symptoms of agoraphobia than before they started the treatment. Participants in the OLD condition were exhibiting 42% fewer symptoms, and participants who did not receive therapy exhibited 22% fewer symptoms than six months ago. Researchers were pleased with the results, concluding in an article they were writing that a new treatment had been found that will be more successful with agoraphobics than previous treatments.
Question #1- do you agree with the conclusion of the researchers? write a paragraph describing an alternative explanation for the result
Question 2- also write a paragraph describing how the experiment might have been designed so as to rule out the alternative explanation that you provided
Yes i agree with the conclusion made by the scientists on the experiment for agoraphobia.
This could be due to psychological factors
:Another explanation could be that each patients' levels of this phobia is variable . However, comparing the findings of each one is more likely to occur if the patients' levels of phobia are equal. To determine whether the tests are effective vs if nothing is done to address the problem, the "none" is compared to the tests. To compare with the "new," the "old" is present. It would be inefficient and necessary to eliminate the "new" if it is neither better nor worse than the old.
Agoraphobia is a fear of being in precarious situations or of not being able to get aid if something goes wrong. A person with agoraphobia could be afraid of riding public transportation.A tragic childhood event, such losing a parent or experiencing sexual assault. suffering a stressful incident, such as a death in the family, a divorce, . a history of mental diseases including depression, bulimia, or anorexia nervosa. misuse of drugs or alcohol.

how many grams of NaCI are needed to prepare a 250ml of a 0.50 M solution
Answer:
Explanation:
250ml=0.25 liter
0.50M means there is 0.50 mole of NaCl for every 1 liter of solvent.
If so, I need (0.25*0.50) mole of NaCl to make 0.50M soln
0.25*0.50=0.125mole
number of mole= given mass/formula mass, therefore for Nacl:
0.125=X/58.44
x=7.305
you need 7.305 gram of NaCl
The mass of NaCl required is 7.31 g
What is the mass in grams of NaCl required to prepare 250ml of a 0.50 M ?The mass of NaCl required is obtained from the molarity and volume of the solution as follows:
Molarity = number of moles/volume(in Liters)Number of moles of NaCl present in 250ml of a 0.50 M wil be:
Number of moles = molarity * volume
volume of solution = 250 mL = 0.25 L
Number of moles = 0.25 * 0.5
Number of moles = 0.125 moles
Number of moles = mass/ molar massmass = number of moles * molar mass
Molar mass of NaCl = 58.5 g/mol
mass = 0.125 * 58.5

You hold a 5-kg book 1.2 meters above the floor for 2 minutes. How much work did you do?
The work done while holding a 5-kg book 1.2 meters above the floor for 2 minutes would be zero.
What is work?
Work is a measure of energy transfer that happens when an item is moved across a distance by an external force that is applied in at least part of the displacement direction. Work may be calculated if the force is constant by multiplying the length of the path by the component of the force operating along the path.
To put this notion into mathematical terms, the work W is equal to the force f multiplied by the distance d, or W = fd. The work done when the force is applied at an angle θ to the displacement is W = fd cos θ. Work on a body is done not only by moving the body as a whole from one location to another, but also by compressing a gas, spinning a shaft, and even producing invisible movements of the particles within a body by an external magnetic force.
Here, W= Fd
W = F × 0 (No displacement occured)
W = 0
Therefore, in this case, the work done is zero.

The DNA sequence capable of pairing with 5’ CGATTAGT3’ is?
DNA is composed of two strands of nucleotides. The bases of these nucleotides form pairs: Adenine with thymine and cytosine with guanine. The complementary strand is 3' - GCTAATCA - 5' .
What is the composition of DNA?DNA is the molecule in charge of carrying genetic information needed for the correct cell functioning.
This polymer is composed of several monomers joined by their extremes. Each monomer has a phosphate group, a sugar, and a base (adenine, guanine, thymine, or cytosine).
DNA is composed of a double, coiled monomeric strand. One of the strand's bases pairs the bases of the other strand (adenine must always pair thymine, while guanine must pair cytosine).
These strands are known as the coding strand and the template strand. During DNA replication, the molecule unwinds to separate the strands, and two new chains are synthesized.
So, what we need to know to answer this question is that bases pairing is as follows,
Adenine (A) ⇔ Thymine (T)
Guanine (G) ⇔ Cytosine (C)
5’ - CGATTAGT- 3’
3' - GCTAATCA - 5' ⇒ complementary strand.

Electrons travel in circles around the nucleus (proton and neutron center of an atom
In a covalent bond, the shared electrons travel around: a. Both nuclei.
What causes an electron to circle?The magnetic force acting on a charged particle is perpendicular to both its direction of motion and the magnetic field when it moves at right angles to the magnetic field. Circular motion may occur from this.
The lowest energy electrons are located on the circle that is most next to the nucleus. The highest energy electron is found on the outermost circle, followed by eight others with greater energies.
Orbitals are the names for these areas of space. Each orbital can only ever have a maximum of two electrons present. Since all electrons with the same amount of energy must inhabit the same zone, according to Bohr, electrons have fixed amounts of energy.
